Multi-photon signatures as a probe of CP-violation in extended Higgs sectors
Shinya Kanemura, Kento Katayama, Tanmoy Mondal +1
We propose a novel signature with four-photon final states to probe CP-violating (CPV) extended Higgs sectors via processes with be…
CP Violation in a Model with Higgs Triplets
Ting-Kuo Chen, Cheng-Wei Chiang, Kei Yagyu
We discuss CP-violation in a model with a real and a complex isospin triplet Higgs fields without introducing any symmetries except for the electroweak gauge symmetry. This corresp…
Gauged breaking as origin of neutrino masses, dark matter and leptogenesis at TeV scale
Toshinori Matsui, Takaaki Nomura, Kei Yagyu
We propose a new mechanism which simultaneously explains tiny neutrino masses, stability of dark matter and baryon asymmetry of the Universe via leptogenesis due to the common orig…
Exploring Wrong Sign Scenarios in the Yukawa-Aligned 2HDM
Shinya Kanemura, Tanmoy Mondal, Kei Yagyu
We discuss scenarios with wrong-sign (WS) Yukawa couplings for the discovered Higgs boson in the Yukawa-aligned two Higgs doublet model. In the WS scenario, Yukawa couplings for do…
Implication of the boson mass anomaly at CDF II in the Higgs triplet model with a mass difference
Shinya Kanemura, Kei Yagyu
A new report for the measurement of the W boson mass has been provided by the CDF II experiment. The measured value of the W boson mass is given to be $m_W^{\text{CDF II}} = 80.433…
Explanation of the mass shift at CDF II in the Georgi-Machacek Model
Ting-Kuo Chen, Cheng-Wei Chiang, Kei Yagyu
The CDF II experiment has recently determined the mass of the boson to be GeV, which deviates from the standard model prediction at $7…
